umm number 2.... so there's like 2 consultants i think.... so one got 500 more/less than the other one (it doesn't matter really, more/less,it's the same both ways...)
so this is how you set it up...
c+(c+500)=18,500 c=the one consultant that gets 500 less so solve!!!
2c+500=18,500 - combine like terms
2c+500=18,500 -500 -500
2c=18,000 -- --- 2 2
c=9,000 c+500=9,500
so the two pays are $9,000 & $9,500 i think...... done!!!!
you used one number that is not 0 or 1 in the first slot, there are a total of 4 possibilities for that single slot
so there are 5 possible numbers to the next slot, because you used one number on the first slot, so there are only a number of 5 possibilities left for the second slot.
Finally then you have 4 numbers for the last slot because you've used 2 numbers already for both the first and second slot
so....
4 x 5 x 4
meaning 4 possibilities times five possibilities times 4 possibilities, these number are based on haw many number of possibilities are available for each slot
Since 0 or 1 can't be in the first digit of the prefix, there are only four other possibilties: 2,3,7, or 9.
Then the second digit will have five possibilites: 0, 1 , and four possibilties -1 because one of the numbers mentioned before would be in the first digit.
For example, if 2 was the first digit, then the second digit could be 0, 1, 3, 7, or 9, which is five possibilities.
Then the last digit would have four possibilities.
For example, If the first two digits were 2 and 3, then the last digit could be 0, 1, 7, or 9, which is four possibilities.
Multiply the 4 possibilities for the first digit, then the 5 for the second, and the 4 for the third. (4)(5)(4)=80

done!!!!
is anyone on? :(
no no #2 not the second problem the first problem

so..... multiply!!!
4 x 5 x 4
20 x 4
80 possibilities!!! - i think
haha i thought you meant the second problem on the assignment not the actual problem number, nikki and tariq sorry >.<
Number 2:
Since 0 or 1 can't be in the first digit of the prefix, there are only four other possibilties: 2,3,7, or 9.
Then the second digit will have five possibilites: 0, 1 , and four possibilties -1 because one of the numbers mentioned before would be in the first digit.
For example, if 2 was the first digit, then the second digit could be 0, 1, 3, 7, or 9, which is five possibilities.
Then the last digit would have four possibilities.
For example, If the first two digits were 2 and 3, then the last digit could be 0, 1, 7, or 9, which is four possibilities.
Multiply the 4 possibilities for the first digit, then the 5 for the second, and the 4 for the third. (4)(5)(4)=80
So I THINK there are 80 possibilities.
me and eric got the same answer so it SHOULD not IS right......
Thanks
whats the ? i can help!
but i need the actual equation
